We've done well on the $5 and $10 Top Dollar machines in the past and we'll play them again on our next trip. Is there a multiple that we should keep in mind when getting an offer? For instance, if playing the $10 machine I'd pass on anything under $500 and take anything above. Does that sound about right or are we being too greedy? Needless to say there have been a few times when we didn't get an offer over $500 and we ended up with a low-ish amount. We also dabbled with the $25 machine but didn't get the bonus feature unfortunately!
